mrrnvc on COATING APPARATUS Application filed June 20,

The invention relates to new and useful improvements in dipping or coating apparatus and relates more particularly to a machine for dipping and forming articles or rubber or analogous materials, such as nip pies, gloves, etc.

An important object of this invention is to provide an apparatus of the above character in which the forming and drying of the article is performed in a continuous operation.

Another object of the invention is to provide an apparatus of the above character having means adapted for disposing the forms in various predetermined positions to insure even distribution of the material.

A stillfurther object of this invention is to provide an apparatus of the above character wherein means are provided for moving as the forms at predetermined intervals to prevent dripping of the material.

These and other objects will be apparent throughout the course of the following description forming a part of this specification in which Figure l is a side elevationof the apparatus disclosing the means for disposing the forms in various positions Figure 2 is a sectional view of a. pair of dipping forms and dipping tanks taken on line 22 of Figure l; and

Figure 3 is a sectional view taken on line 3-3 of Figure 1 showing the means for moving the forms to one of its material distributing positions.

Referring to the drawings in detail, 1 designates an endless supporting belt or conveyor disposed about a series of spaced and suitably supported guide wheels 2.

Disposed upon opposite sides of said conveyor are a pair of aligned laterally eXtending arms 3 pivotally secured to said conveyor for axial turning movement, said arms being substantially rectangular in cross section for a purpose to be hereinafter more fully eX- plained.

Disposed upon each of the free ends of said arms 3 and at right angles thereto is a U- shaped clip 4 adapted to frictionally engage and detachably support a form 5, the latter,

in this instance being for the formation of" a finger cot. Secured to each of the arms 3 intermediate its ends, and held against relative turning movement thereto is an actuating wheel 6 adapted to engage and be rotated by a track 7 disposed between and extending beyond a pair of dipping tanks 8.

' Disposed beneath the upper flight of the conveyor are a pair of aligned spaced tracks 9adapted to engage and rotate the wheels 6 a for revolving the forms thereby to drythe articles. A supporting guide rail 10 is disposed intermediate the adjacent ends of the tracks 9v and elevated above the latter for engaging one of the faces of the arms 3 for sliding movement thereon wherebythe forms are held in vertical position for a predetermined time to facilitate the even distribu- 7 all en a e the tracks 7 for causin the forms y g s V c:

to assume the position shown in dotted lines whereby the same are dipped into and removed" from the tanks in a continuous operation. During the continued movement of the rotatably supported forms the wheels 6, engage the tracks 9, the latter being of such length so as to move the forms to a vertical position whereupon one of the flat faces of the rectangular arms 3 engage with and are slidably supported on the guide member 10 during the forward movement of the form .for a-predetermined time. g

It is to be understood that the conveyor may be ofsuch length so as to completely dry the articles during the continued movement thereof or other means not shown such as fans or the like may also be utilized for forcibly drying the articles.

Having thus described my invention what I claim as new and desire to secure by Let-' ters Patent is V 1. A dipping machine, comprising a con- 'veyor pivotally mounted article forming means carried by said conveyor, a dipping tank, and a longitudinally extending track.

disposed beneath the conveyor adjacent said tank adapted for frictional engagement with said article forming means for moving the latter into and out of said tank.

2. A dipping machine, comprising an end less conveyor, a series of spaced laterally extending arms of substantially rectangular cross section rotatably secured to said conveyor, article forming means secured to said arms, a dipping tank, means for moving the forms into and out of said tank, and means for moving said article forming means to varying positions where by even distribution of the material upon the forms is facilitated.

3. A dipping machine, comprising an endless conveyor arranged to provide upper and lower horizontally disposed flights, a series of spaced rotatably supported forms carried by said conveyor, a dipping tank means disposed beneath the lower horizontal fiight of the conveyor for moving the forms into and out of said tank and means disposed between the upper and lower horizontally extending flights of the conveyor for moving and retaining the forms in varying positions whereby even distribution of the material is facilitated.

l. A dipping machine, comprising an endless conveyor disposed so as to provide upper and lower horizontal flights, a series of spaced disks rotatably secured to said conveyor, a pair of laterally extending arms carried by said disks of substantially rectangular cross section, article forming means secured to said arms, a dipping tank, a longitudinally extending track disposed beneath the lower horizontal flight of the conveyor adjacent said tank for frictionally engaging the disks to move the forms into and out of said tank, means disposed between the upper and lower horizontal flights of the conveyor for moving the forms to vertical positions, and means engaging the arms for retaining the forms in said vertical position for a predetermined time.

5. A dipping machine, comprising an endless conveyor, a dipping tank beneath said conveyor, a series of spaced rotatably supported laterally extending arms carried by the conveyor, a disk carried by each of the said arms intermediate their ends, an article forming member carried by each of said arms adjacent its free end and means for frictionally engaging said disks for rotating the arms, whereby the forms are moved into and out of the said tank.

6. A dipping machine comprising an endless conveyor, a dipping tank beneath said conveyor, a series of rotatably supported laterally extending arms carried by said conveyor, each of said arms having a plane face,

a disk carried by each of said arms, a dipping form secured to each ofsaid arms opposite the plane faces of the latter, means for frictionally engaging the disk to move the name to this specification.
